Heating assembly with inductive coil

Abstract

A heating assembly includes two permanent magnets arranged in a spaced manner to define a path therebetween for passage of a plurality of stainless steel nails, and an inductive coil wound around an extending direction of the path in such a way that the inductive coil has a number of loops arranged along two opposite sides of the permanent magnets. Thus, when the stainless steel nails move through the path, the inductive coil can receive a low-intensity operation current to heat the stainless steel nails to a predetermined temperature.

1 . A heating assembly for heating a plurality of stainless steel nails, comprising:
 two permanent magnets arranged in a spaced manner to define a path therebetween for passage of the stainless steel nails; and   an inductive coil wound around an extending direction of the path in such a way that the inductive coil has a number of loops arranged along two opposite sides of the two permanent magnets.   
     
     
         2 . The heating assembly as claimed in  claim 1 , wherein the inductive coil has the same number of loops at the two opposite sides of the permanent magnets respectively, and two distal ends of the coil located at the same side of the two permanent magnets. 
     
     
         3 . The heating assembly as claimed in  claim 1 , wherein the inductive coil has a different number of loops at the two opposites sides of the permanent magnets respectively, and two distal ends of the coil located at different sides of the two permanent magnets. 
     
     
         4 . The heating assembly as claimed in  claim 1 , wherein the loops of the inductive coil extend along a direction parallel to the extending direction of the path. 
     
     
         5 . The heating assembly as claimed in  claim 1 , wherein a number of the loops of the inductive coil extend along a direction vertical to the extending direction of the path.
